Different aspects of a drill bit

The Spiral

The spiral in a bit is the part that controls the rate of chip removal. There are mainly two types to this. The fast spiral drill bit is used in high feed rate applications under low spindle speeds, where removal of a large volume of chips is required. Low spiral ones are used for cutting applications where high cutting speeds are used.

The Point Angle

It is the angle formed at the tip of the bit, and is determined by what type of material the drill bit will be drilling in. Soft material requires sharp angle, while harder materials require larger point angles. The wandering, chatter, wear rate, and hole shape is influenced by the point angle.

Lip Angle

The lip angle determines the amount of support that is provided to the cutting edge. Under the same amount of point pressure, a greater lip angle will cause the bit to cut more aggressively than the bit with smaller lip angle. The proper amount of lip clearance is determined by the point angle.

The Length

The length of the bit is responsible for determines the stiffness of the bit and the accuracy of the resulting hole, along with the depth of the hole. Longer drills can drill deeper, but are a little flexible when it comes to the accuracy of the hole’s location.

Most drill bits have straight shanks, but for heavy duty drilling, bits with tapered shanks are used. Bits are made with a variety of materials.
